views are stored as property svk:view:NAME on a directory.
Suppose you have svk:view:ptest set on //project,
you can refer to it by //^project/ptest.
That is,
a caret,
and then path holding the property,
a slash,
and the name of the view.

You can now use //^project/ptest as a target for normal svk commands like ls,
checkout and diff.

Here is an example for the value of the property:

&:/project/trunk
-*
dir1 dir1
util src/deep/util

The first line is the base of the view. The &: sign means the root of a mirror, so the view can still be used even if other people mirrored the repository to a different path in their local repository.

The second line means taking out all the content under the root. And then take dir1 back, stick the directory src/deep/util to util under the view. So running svk ls //^project/ptest you should see:
